Performers in costume perform in the rain during the parade on the second day of the Notting Hill Carnival in west London on August 31, 2015. Nearly one million people are expected by the organizers Sunday and Monday in the streets of west London's Notting Hill to celebrate Caribbean culture at a carnival considered the largest street demonstration in Europe. The Notting Hill Carnival started in the 1960s, when the area had a large population of immigrants recently arrived from the Caribbean and was notorious for its slums – a far cry from today when it is one of London's most expensive places to live.
